signals easily and accurately.
The Signal Measurement Radio (SMR) receiver
allows an information radio station operator to
measure accurately the level of his/her AM
signal to comply with FCC rules. It is also
useful for measuring AM-band noise, before
station installation to
determine the quietest frequency on which to
broadcast. AM signal intensity is displayed as a
two-digit read-out on the lighted front panel
LCD display. Batteries are included and
pre-inserted, so the unit powers up on-band
and ready to operate. Included are illustrated
instructions from us detailing procedures for
measuring AM signals and AM-band noise.
yourself that your station never exceeds FCC
The SMR Receiver is the first device of its kind
capable of measuring and displaying AM signal
levels with a useful level of precision.
Our project manager Tom Coviak explains it this
way: "The SMR Receiver provides a digital LCD
readout that correlates reliably to scientific
measurement equipment…for about one-hundredth
Further, Tom recommends, "It’s
important to have a means of monitoring, not
only to make sure your station complies with FCC
limits but also so you can spot adverse changes
in your signal that could point to equipment
concerns within your station or its
Issues involving an antenna system, for example,
are much less expensive to correct sooner than
later, since they can affect electronic
Coviak advises, “Now
every operator can afford such a receiver, and
it should be part of the basic toolkit for their
We provide SMR
Receivers with all new radio station packages;
and they can be obtained separately, as well.

Information Radio Stations is a generic term synonymous with Travelers
Information Stations (TIS), Highway Advisory Radio Stations (HAR) /
Highway Information Systems & Low Power Radio Stations (LPR). Operation
of the stations is governed by FCC Part 90.242 Rules. A FCC license is
required. Information Radio Stations may be fixed or portable.
Subcomponents may include transmitter, antenna and ground system,
digital voice player, wattmeter, cabinet with conventional or Corbin
locks, lightning arrestors for RF, power and telephone lines, coaxial
cable. Most stations employ black maximized antennas to discourage ice
accumulation and security measures to prevent unauthorized program
access. Options include synchronization, battery backup, solar power,
remote programming by local, network or telco, multi-station audio
distribution via RF or LAN / WAN or wireless network.
